Figure l is a partial left-hand side view of herein shown, an upturned tail G33, limited as a loom with one embodiment of myinvention to its angular movement by stops 3 4, as

35 applied thereto, the lay being shown in its clearly shown in Figs. 3 and 4, the upper end 85 rearmost position. Fig. 2 is an enlarged top of the tail being located in the path of some or plan view of the mechanism at the leftportion of the lay A3, such as the hand-rail hand side of the loom as shown in Fig. l, withA R, so that when the shuttle is properly boxed the corresponding shuttle-box,a shuttle thereand the shuttle-feeler is in the position shown 4o in, and a feeler arranged to coperate with in Fig. 4 the severing means will be operated 9o the iillingin the shuttle. Fig. 2 isadetached as the lay beats up.

View of the actuator forming a part of the ltWill be understood that the shuttle-feeler controlling means for the filling-supplying has a detecting movement only when a fresh mechanism to be described. Fig. 3 is a crosssupply of filling is to be inserted in the shutsectional view of the loom looking toward the tle, as in Patent No. 568,455, referred to, so 95 inner end of the filling-supplying mechanism that the cutting-blades will be operated only located at the right-hand side of the loom; at such time, provided the shuttle is in the and Fig. 4 is a similar view, but with the lay shuttle-box B10, to sever the thread of the forward, showing the feed-severing means in ejected filling-carrier. The movable blade operative position. omis returned to normal open position by the roo engagement of the tail e"i3 with a sprin g-fm ger si, shown as attached to the arm fax, when the said tail is released bythe operating portion of the lay. \Vhen the feeler on its dctecting movement encounters and is stopped by the improperly-boxed shuttle, the slotted portion of the link (f1 permits such stoppage even though the arm (f2 of the rock-shaft (Z1 may be in the position shown in Fig. 4, such stoppage of the feeler preventing the operation of the filling-supplying mechanism in usual manner.

Referring now to Figs. l and 2, l have shown the front plate i315 of the shuttle-box B12 at the opposite or left-hand end of the lay provided with bearings D15 for a rock-shaft 111, having rigidly attached thereto the fillingfecler Z117, `shown as an upturned and rearwardly-curved fingerextendingover the shuttle-box and adapted when depressed to engage the fillingon the filling-carrier F'in the shuttle when the latter is properly boxed. ly mounting the feeler on the front plate of the shuttle-box the feeler is positioned properly relatively7 to the shuttle when the position of the plate is changed, such change being made as the shuttle wears. lVere the feeler mounted on the lay, itwould be stationary relative to the shuttle, the position of which might be varied. A spring S10, fixed at one end and at its other end attached to the rock-shaft (11, normally maintains the feeler elevated above the path of the shuttle, a suitable stop 1118 limiting the movement of the rock-shaft due to the spring. The inner end of the feeler rock-shaft is provided with two branches b1 b2, Fig. 1, located substantially one above the other and slightly flared or bent oppositely at their free ends, while a dog b21, fast on the rock-shaft, is herein shown as provided at its extremity with a roll b2, the branches and dog extending toward the breast-beam. The bearing e30 on the latter supports an upturned rocking plate or bunter (L31 in the path of the roll 1122 and normally maintained elevated by a spring s1, stiffer than the feeler-springsw, so that as the lay comes forward theroll will engage and travel upward upon the bunter, rocking the shaft o16 in the direction of the arrow (l to depress the feeler. rlhe amount of filling on the filling-earrierF determines the eXtentof such movement of the feeler, and when the fecler is stopped by engagement with the filling the bunter (L31 will yield more or less as the lay completes its forward movement.

The usual shipper-handle 39, Fig. 2, moves in the notched plate c3". At U1 is pivoted a knock-off lever fr, normally resting against or adjacent the shipper-handle, the free end of the lever being acted upon by the weft-fork mechanism when it is desired to release the shipper-handle, and thereby through usual means stop the loom.

The weft-fork mechanism herein illustrated is substantially that shown in United States Patent- No. 529,943, comprising a stand ff,

mounted on the breast-beam and provided with a guideway in which aslideff is adapted to reciprocate, the weft-fork 612, pivoted at D10 on the slide, having a rearwardly-projecting tail i113 to be engaged by a hook D14, pivoted on the upper end ofthe weft-ham mer A1'J when the filling is absent as the lay beats up.

A latch (Z5 is pivoted at d1 on the slide D and has on its under side a cam l2, the free downtnrned end of the latch being adapted to at times operate the knock-off lever b5, a wedge d, longitudinally movable in the slide Z1, having a cam 14 on its upper side to cooperate with the latch-cam 12, the outer edge of the wedge being downturned, as at 44, to meet a shoulder 45 under certain conditions, said shoulder forming a part of the stand L7, all substantially as in said Patent No. 529,943. On the outer side of the stand b1 I have mounted a sliding aetuatorm, (shown separately in Fig. 2%) longitudinally slotted at m to receive retaining-screws m2, extended into the stand, the rear end of the said actuator having a lateral lug or projection m3, adapted to be engaged by a hook m1, pivoted at m5 on an ear A20 on the weft-hammer, said ear being offset to clear the stand and the actuator. The outer end m6 of the hook is T-shaped and is acted upon by a leaf-springr on the ear A20 to frietionally retain the hook in operative or inoperative position until positively moved therefrom. The hook is provided with a laterally-extended pin or stud m7, herein shown as near its head end and in the path of movement of one or other of the branches 1119020 of the feeler rock-shaft b1, At each forward beat of the lay the upper branch b1" will slide over or above the pin m7 to thereby maintain the hook m4 inoperative. lVhcn, however, the filling in the shuttle has been exhausted sufficiently to permit a greater movement of the feeler into the shuttle, the branch b2" will be raised sufficiently to pass beneath and lift the pin m1 as the lay beats up to thereby depress the rear end of the hook to engage the lug or projection mg of the actuator m, so that the latter will be moved outward by the weft-hammer. The outer end of the slide will at such time engage an upturned arm (Z211, fast on the rockshaft d, turning the latter sufficiently to operate the filling-supplying mechanism in well-known manner to therebyinsert a fresh supply of filling into the shuttle before complete exhanstion of the filling then in the shuttle. lVhen the shuttle, with its fresh supply of filling, thereafter enters the shuttlebox Z212, the feeling movement of tliefeeler will be suspended and the rock-shaft L15 will be so positioned angularly as to cause the branch o1 to engage the pin m7 and depress it to move the hook m1 into inoperative position. It

will thus be seen that the controlling means for the filling-supplying mechanism is actuated by or through the weft-hammer in a positive manner and that the cooperation of said controlling means and weft-hammer is IOO IIC

governed by or through the feeler and effected upon exhaustion of the filling in the shuttle to a predetermined extent, the feeler being adjusted angularly with relation to the branch D20 to bring the latter into operative position only when a small and predetermined amount of filling is left upon the filling-carrier.

The controlling means for the filling-supplying mechanism includes the rock-shaft d', the actuator m, and the usual connections between the rock-shaft d and transferrer, as Patent No. 529,940, referred to, and the feeler-l controlled rock-shaft o16, with its branches b1 Z220, may be termed a governing"7 device for said controlling means. Should the filling fail, then the usual weft-fork mechanism will operate, and upon the first outward movement of the slide D the end 44. of the wedge d6 will engage the shoulder 45 to permit the latch (Z5 to drop on the knock-off lever, as in Patent No. 520,943, and at the second outward movement of the slide the latch, then behind the knock-off lever, will push the latter to release the shipper-handle and stop the loom. An arm (130 is loosely mounted on the rock-shaft d and is held by a spring SX against the outer end of the slide o, the spring pushing the. slide inward, a depending extension C132 on the arm engaging the usual actuating-pawl of the take-up mechanism when the arm d3() is rocked by the outward movement of the slide, so that the take-upwill not be actuated at either the first or second movement of the said slide.

My invention is not restricted .to the construction and arrangement herein shown, as the same may be modified or rearranged without departing from the spirit and scope of myinvention. Neither is my invention restricted to the use of the weft-fork mechanism herein shown.
